       6. An apparatus for generating super-high pressure according to claim 4, wherein said pair of split casing bodies are brought into tight contact with each other at the composition plane by the fluid pressure generated by said pressing force. 
     
     
       7. An apparatus for generating super-high pressure comprising: a plurality of moveable bodies arranged to oppose each other so as to define an internal space for receiving an article to be pressed, said bodies being moveable toward said space;   a casing defined by a pair of split casing bodies, said pair of split casing bodies being in contact with each other on a composition plane, the casing having a cavity for containing said plurality of moveable bodies therein and having a plurality of fluid pressure chambers contiguous to said cavity, said fluid pressure chambers being adapted to receive pressurized fluid therein for moving said bodies inwardly toward said internal space; and   a distinct fluid pressure generating means integral with each of said split casing bodies at opposite, outer surfaces thereof, said fluid pressure generating means generating fluid pressure to be introduced into said pressure chambers for a pressing force applied from outside of the casing, and said pair of split casing bodies being brought into tight contact with each other at the composition plane by the fluid pressure generated at the opposed outer surfaces.   
     
     
       8. An apparatus for generating super-high pressure according to the claim 7 wherein said fluid pressure generating means comprises: rams integral with and protruding from said casing;   cylinders having openings and slideably receiving said rams; and   head covers closing the openings in said cylinders to seal fluid between said rams, and pressing the fluid using the force which is applied from outside of the casing.   
     
     
       9. An apparatus for generating super-high pressure according to claim 7 wherein said plurality of moveable bodies includes six split spherical bodies obtained by equally dividing a sphere. 
     
     
       10. An apparatus for generating super-high pressure according to claim 7 wherein said pressure chambers respectively contain pistons contacting the outside of said moveable bodies, and operating on said moveable bodies so as to move said moveable bodies inwardly toward said internal space. 
     
     
       11. An apparatus for generating super-high pressure comprising: a casing having first and second casing bodies, said casing bodies being in contact along a plane, having a cavity defined therebetween and at least one pressure chamber being formed in each of said casing bodies;   a plurality of bodies disposed in said cavity and movable toward the center of said cavity, said bodies defining a space at a central position thereof;   distinct fluid pressure generating means integral with each of said casing bodies and supplying fluid pressure to transmit a force to each of said movable bodies to force them to move toward the center of said cavity; and   pistons disposed in said pressure chambers, each of said pistons being in contact with one of said movable bodies, said fluid pressure acting on said pistons to transmit a force to said movable bodies, said pistons having a concave surface and said movable bodies having a convex surfaces, said pistons and said movable bodies being in contact at their respective concave and convex surfaces, respectively.
